Background: Melanoma is a malignant tumor that originates from the skin's melanocytes and has the highest death rate from skin cancer. Developing more efficacious anticancer medications with fewer adverse effects is the key to effective cancer management. Natural products are considered relevant and cost-effective sources of treatment.

Nutraceuticals are principally extracted from natural products that are frequently safe and well-tolerated. Lycopene and berberine are natural plants with a wide range of beneficial effects including protective activities against metabolic disorders such as diabetes and cardiovascular diseases. These compounds might be considered technically more as a drug than a nutraceutical and could be prescribed as a product.

The endoplasmic reticulum (ER) is the place where proteins and lipids are biosynthesized and where transmembrane proteins are folded. Both pathological and physiological situations may disturb the function of the ER, resulting in ER stress. Under stress conditions, the cells initiate a defensive procedure known as the unfolded protein response (UPR).

Due to its poor regenerative capacity, the heart is specifically vulnerable to xenobiotic- induced cardiotoxicity, myocardial ischaemia/reperfusion injury and other pathologies. Nuclear factor erythroid-2-related factor 2 (Nrf2) is considered as an essential factor in protecting cardiomyocytes against oxidative stress resulting from free radicals and reactive oxygen species. It also serves as a key regulator of antioxidant enzyme expression via the antioxidant response element, a cis-regulatory element, which is found in the promoter region of several genes encoding detoxification enzymes and cytoprotective proteins.

Objectives: Liver is the most important and functional organ in the body to metabolize and detoxify endogenous compounds and xenobiotics. The major goal of the present narrative review is to assess the hepatoprotective properties of hesperidin against a variety of natural and chemical hepatotoxins via different mechanisms.

Evidence Acquisition: Scientific databases such as Scopus, Medline, Web of Science and Google scholar were thoroughly searched, based on different keywords.

Curcumin, an orange-yellow lipophilic polyphenolic molecule, is the active component of Curcuma longa, which is extensively used as a spice in most of the Asian countries. This natural compound is able to interact with a large number of molecular structures like proteins, enzymes, lipids, DNA, RNA, transporter molecules, and ion channels. It has been reported to possess several biological effects such as antioxidant, anti-inflammatory, wound healing, antimicrobial, anticancer, antiangiogenic, antimutagenic, and antiplatelet aggregation properties.

A new series of novel benzo[c]acridine-diones possessing pharmacophoric elements of antitubulins with central dihydropyridine bridge were designed and synthesized as potential anticancer agents and tubulin polymerization inhibitors. The cytotoxic activity of the synthesized compounds was evaluated against eight cancer cell lines including MCF-7, A2780, HeLa, HepG2, DU145, A549, PC3, and LNCAP cancer cells and normal cells human umbilical vein endothelial cell (HUVEC) through 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay, wherein β-lapachone and combretastatin A-4 were used as positive controls. Some of our compounds (4c and 4g) showed significant cytotoxic activity on cancer cells with IC values in the range of 5.

Acrylamide (ACR) is extensively used in industrial areas and has been demonstrated to induce neurotoxicity via oxidative stress and apoptosis. In this study, we assessed the probable protective effects of thymoquinone (TQ), an active constituent of Nigella sativa, against ACR-induced neurotoxicity. ACR (50 mg/kg, i.

Article Synopsis
  • The study investigates the patterns of NSAID prescriptions in Northeastern Iran, highlighting the risks of adverse effects like bleeding and gastrointestinal issues due to inappropriate use.
  • About 19.3% of prescriptions were for NSAIDs, with diclofenac being the most commonly prescribed, and a notable number of prescriptions involved the simultaneous use of multiple NSAIDs.
  • The findings suggest a need for improved prescribing practices and education for healthcare providers to reduce the risks associated with NSAID use.

Introduction: Numerous adverse effects of antidepressants as well as the attitudes of breastfeeding mothers, who prefer to consume herbal medicine rather than chemical drugs, encouraged us to assess the effects of saffron (Crocus sativus L.) on mothers suffering from mild-to-moderate postpartum depressive disorder.

Methods: A double-blind, randomized, and placebo-controlled trial was conducted on 60 new mothers who had a maximum score of 29 on the Beck Depression Inventory-Second Edition (BDI-II).

Metabolic syndrome (MetS), characterized by a cluster of metabolic abnormalities including hypertension, obesity, type 2 diabetes mellitus (T2DM) and dyslipidemia, is a well-known cardiovascular risk factor (CVRF). Cardiovascular disease (CVD) represents a massive healthcare burden worldwide. In recent years, with regard to the adverse effects of synthetic drugs, increasing attention has been paid by researchers to herbal medicines for a variety of disorders such as CVD.

Metabolic syndrome (MetS) is a clustering of risk factors including high blood glucose, dyslipidemia, hypertension, and obesity that lead to the increased risk of type 2 diabetes mellitus and cardiovascular diseases (CVDs), which are among leading causes of death in the world. Metabolic syndrome increases the risk of type 2 diabetes mellitus and CVDs by approximately five and three folds, respectively. Therefore, it is of vital importance to manage such conditions with herbal options which have less undesirable adverse effects and may be more efficacious in comparison with synthetic options.
